Southbury Police are investigating a case of who took 100 gallons of cooking oil.  The Newstimes reports that Police were called by a Main Street business last week saying the waste vegetable cooking oil had been stolen from a holding tank.  Used cooking oil can be sold to recyclers, who turn it into profitable yellow grease for use in products like biodiesel and shampoos.  A bill was approved by the Connecticut General Assembly shortly before adjournment to double the maximum prison time for stealing cooking oil.  It was vetoed by Governor Lamont.
